Gets the type of socket operation most recently performed with this object.
Assembly: System.Net (in System.Net.dll)
This property describes the asynchronous socket operation that was most recently completed using this SocketAsyncEventArgs object. The value of this property will be SocketAsyncOperation.None until the SocketAsyncEventArgs instance is used to begin an asynchronous socket operation. The property will then be set to the type of operation being performed in the methods that take the SocketAsyncEventArgs as a parameter. This property more easily facilitates using a single completion callback delegate for multiple kinds of asynchronous socket operations.
Calling an asynchronous socket method on the System.Net.Sockets.Socket class sets this property value. This property is intended for use with the SocketAsyncCallback completion routine implemented by the application.
